Definitions

  • This invention relates to mixing apparatus for mixing two fluids. Particularly, but not exclusively, the invention relates to the field of beverage preparation, and more specifically to the field of automatic frothed milk beverage preparation.
  • full automatic espresso appliances provide the function of automated cappuccino brewing, in which coffee is brewed, and frothed milk is prepared. In most cases, steam is used for heating and frothing the milk, in a similar manner to a barista.
  • milk frothing modules have been developed. Normally, these modules are removable from the base appliance, as all parts in contact with milk need to be cleaned.
  • the milk frothing function typically operates by heating up water in a thermoblock within the coffee machine to generate steam, which then passes to the milk frothing unit.
  • the frothed milk is used for milk recipes generally, and a cappuccino is one example.
  • milk frothing unit comprises an internal milk container and an external part. When they are coupled together, a set of passageways is defined, including a riser passage along which milk from the inside of the milk container is drawn, up to a mixing chamber. In the mixing chamber, the milk is mixed with steam which has been delivered to the milk frothing unit from an external inlet. The steam is used for heating, and it may also be mixed with air for frothing.
  • This type of milk frothing unit is for example described in each of EP 3735874 , WO2019/129599 and WO 2019/129515 .
  • a mixing apparatus comprising:
  • each set of passageways provides mixing of the liquid in the first, inner, container with a fluid (i.e. liquid or gas) provided to the external entry port of the second container.
  • the liquid rises up a riser passage to a mixer chamber.
  • different mixing characteristics may be obtained, for example for mixing different pairs of fluids or for mixing the same pair of fluids but in a different ratio, or mixing with different other properties such as the amount of mixing with air for creating a foam.
  • the sets of passageways may be for mixing milk and steam.
  • the externally introduced fluid may be water, and the mixing apparatus mixes a first liquid in the container with water, for example to dilute and heat the first liquid.
  • the different sets of passageways for example have different passageway dimensions and/or different flow restrictions.
  • Flow restrictions are for example used to tune the flow rates through the different passages, and these can be tuned differently in the different sets of passageways.
  • the mixing chamber is basically a volume where the fluid and liquid meet, before being provided as an output from the apparatus.
  • passageways There may be exactly two sets of passageways, but there may be more.
  • a square (from above) first, inner, container may enable four different passageway designs to be defined.
  • the first container may comprise a set of outer walls, wherein:
  • one wall of the second, outer, container is provided to define both sets of passageways, whereas different walls of the first, inner, container are used to define the different sets of passageways.
  • the first container may comprise a first opening between an inner volume of the first container and the first riser passage and a second opening between the inner volume of the first container and the second riser passage.
  • Each opening allows the passage of the liquid into the associated riser passage. By having only one opening in use, the liquid can only reach the riser passage that is in use.
  • a closing member may be provided for closing one of the first and second openings in dependence on the orientation.
  • the riser passage that is not in use is isolated from the contents of the first, inner, container.
  • a locking arrangement is for example provided for locking the first container to the second container.
  • the locking position provides the required interaction between the two containers to define the first or second set of passageways in a sealed manner.
  • the locking arrangement may comprise the closing member for closing of one of the first and second openings in dependence on the orientation.
  • the closing of an opening is an automatic part of coupling the first and second containers together.
  • the locking arrangement comprises a rotary shaft for displacing the first container laterally into the second container and a head for driving the shaft, wherein the head is also for closing one of the first and second openings which is located at the open side.
  • the rotary coupling enables lateral coupling of the two containers, as well as closing the unused opening.
  • the first container comprises a first valve for the first opening and a second valve for the second opening
  • the second container comprise a valve actuator for opening one of the valves such that the other valve functions as the closing member.
  • the first container may have a first, upright axis, and the first and second orientations are at 90 degrees with respect to each other about the first axis. This enables two adjacent sides of the first, inner, container which may have channels in them to be covered by the second container. This still enables the first, inner, container to be a lateral sliding fit into the second, outer, container.
  • the first container may have a first, upright axis, and the first and second orientations are at 180 degrees with respect to each other about the first axis. This enables only a single location to be needed for sealing the unused opening leading to the unused riser passage.
  • the second container may have at least one open side so that the first container is received as a lateral sliding fit into the second container through the open side. This is one way to couple the two containers together. An alternative is for one to be slid into the other from above.
  • the apparatus may be used for mixing various fluids, generally for beverage preparation.
  • the first container is for containing milk and the external entry port is for steam, and at least one of the first and second mixing chambers is for mixing milk, steam and air.
  • the apparatus is for example a milk frothing unit for a coffee maker such as an espresso machine.
  • the apparatus may further comprise a first air passage which leads to the first mixing chamber in the first orientation and a second air passage which leads to the second mixing chamber in the second orientation.
  • the air passage is used for frothing, in addition to the heating provided by steam.
  • the apparatus is for example adapted to provide different milk frothing characteristics in the first and second orientations.
  • a user can select the characteristics of the milk froth by selecting an orientation of the first, inner, container relative to the second, outer, container.
  • the different frothing characteristics may for instance be different temperatures or different percentage of foam.
  • the apparatus may be adapted to provide different flow rates of milk along the first and second riser passages. This may be achieved with different passageway dimensions and/or different flow restriction dimensions.
  • the invention also provides a coffee machine comprising;
  • the invention provides a mixing apparatus comprising inner and outer containers which define mixing fluid passageways between them.
  • the inner container can be received in the outer container with at least two different orientations.
  • Each orientation forms a different set of passageways each including a mixing chamber and a riser passage which leads from the inner container to the mixing chamber.
  • the different orientations create different designs of the passageways, to give different mixing functionality.
  • the mixing apparatus may be used for mixing any two fluid flows (one being liquid from the inner container).
  • the mixing may be for the purposes of heating and/or for the purpose of dilution and/or for the purpose of frothing (or foaming). It is of primary interest for preparation of beverages or liquid food, such as heated milk, tea, soup, hot chocolate etc.
  • the mixing apparatus is a milk frothing unit for receiving steam delivered to it by an espresso coffee machine.
  • Figures 1A and 1B show am example of an espresso coffee machine 10.
  • Figure 1A shows a perspective view and
  • Figure 1B shows a view from in front.
  • This example is a bean-to-cup machine, although other options are possible.
  • main body 12 which houses a water reservoir, a water heater and a reservoir for receiving coffee beans.
  • a water reservoir for receiving coffee beans.
  • the machine comprises a coffee output 14 from which the espresso drink (without milk) is output.
  • the coffee output 14 faces downwardly and is located over a drip tray 16.
  • Figures 1A and 1B also show a user interface 18 for receiving user selections, such as for water selection and for other drinks selections. At least some of the drinks selections relate to drinks recipes which include frothed milk and therefore require the generation of steam. There may also be an option for the generation of steam without being part of a drink selection, for example to enable the user to generate heated and/or frothed milk independently of any drink to be made by the machine.
  • An output nozzle 20 is provided for delivering steam for milk frothing or hot water, depending on user selection at the user interface 18.
  • the steam output may be used for heating and/or frothing milk, and the option of a hot water only output gives additional options to the user, for example for making soup, tea, hot chocolate etc. It is noted that instead of a single nozzle, there may be separate nozzles for steam and for hot water (not shown).
  • the output nozzle 20 is located in a docking region 21 for receiving a drinks vessel or a milk frothing unit.
  • the invention relates to a mixing apparatus, for example for creating frothed milk. It may for example be a modification to the mixing apparatus as disclosed in WO 2019/129599 and WO 2019/129515 , although the invention has more general applicability.
  • Figure 2A shows a mixing apparatus 100 as disclosed in WO 2019/129599 and WO 2019/129515 .
  • the mixing apparatus comprises: a first, inner, container 110; a second, outer, container 120, adapted to receive the first, inner container; and a seal 130 disposed between the first and second containers.
  • the seal is for example a press fit into a side wall of one of the two containers so that when the two containers are assembled, the seal is sandwiched between them.
  • the mating between the seal and one of the containers forms a closed channel arrangement which defines the fluid paths for milk and steam.
  • the seal may be a single seal or may be formed of different parts.
  • the seal may be two shot (2K) molded into the second container, or else it may be a separate seal which is removable from a recess in the second container.
  • the mixing apparatus comprises a channel arrangement 140, which is defined by the seal 130 and the first container 110 when the mixing apparatus is assembled.
  • the first container 110 comprises a raised channel portion 145, which further defines the channel arrangement.
  • the channel arrangement connects a first port 150 at the bottom of the first container and a mixing chamber 160 near the top of the first container.
  • the second container comprises an external entry port 175 (see Figure 2B ) connected to a first seal port 170 provided in the seal 130.
  • the channel arrangement 140 further connects the first seal port 170 to the first port 150 and the mixing chamber 160.
  • Figure 2B shows the mixing apparatus 100 of Figure 2A in an assembled state.
  • the second container 120 further comprises the external entry port 175 for receiving steam, for example from the espresso coffee machine. This steam is then provided to the first seal port 170.
  • the second container further comprises a third port 180 that in assembled condition is connected to the mixing chamber 160 of the first container, thereby allowing the contents of the mixing chamber to be easily obtained from the mixing apparatus.
  • Figure 3A shows a detailed view 200 of the channel arrangement 140 of the mixing apparatus of Figure 2A .
  • the channel arrangement 140 may be divided into several portions according to the operation performed by each portion.
  • milk may be provided to the first container 110 and steam may be provided to the first seal port 170 (via external entry port 175).
  • steam As steam enters the channel arrangement 140, milk 215 is drawn from the first container into a milk passage 210 (herein after also referred to as a first channel portion or riser passage 210) via the first port 150.
  • the steam 225 enters a second channel portion 220 via first seal port 170 and then travels through a third channel portion 230 and into the mixing chamber 160.
  • the flow of steam generates a negative pressure in the first channel portion 210 (i.e. the riser passage), thereby drawing the milk along the first channel portion 210.
  • the milk 215 is drawn along the first channel portion 210 until it meets the intersection of the three channel portions, where the flow of steam draws the milk and steam into the third channel portion 230 which terminates at an end 235 which opens into the mixing chamber 160.
  • the third channel portion 230 may be adapted to impart a Venturi effect on the milk and steam as they pass through the third channel portion.
  • the steam is used to heat the milk and it operates the Venturi (i.e. a reduced pressure) to suck the milk up the first channel portion 210.
  • Venturi i.e. a reduced pressure
  • Air is introduced at the end point 235, by suction due to the flow speed.
  • the introduced air provides bubbles for the desired frothing.
  • the Venturi effect may be achieved by simply restricting the cross sectional area of the third channel portion 230 relative to the first 210 and second 220 channel portions.
  • the increase in speed of the milk and steam as they enter the third channel portion in combination with the drawing in of air defines the frothing performance of the mixing apparatus, and the pressure differential prevents the milk and steam from flowing down the incorrect channels.
  • the first channel portion 210 is typically vertical in use and extends up from the (milk entry) first port 150. At the top it meets the second channel portion 220 to one side which has a steam entry port at its remote end, and it meets the third channel portion 230 to the other side, which has the mixing chamber 160 at its remote end.
  • the channel arrangement 140 thus has a T-shape
  • the seal 130 has a corresponding T-shape.
  • Figure 3B shows a simple illustration of the intersection of the three channel portions.
  • the milk 215 flows along the first channel portion 210 due to the negative pressure generated by the steam 225 flowing from the second channel portion 220 to the third channel portion 230.
  • the channel widths are reduced as the milk and steam enter the third channel portion, thereby imparting a Venturi effect on the milk and steam flows, which is used to draw the milk along its channel.
  • Air is drawn in at the end 235 of the third channel portion 230 so that there is milk, steam and air mixture entering the mixing chamber.
  • the aim of the mixing chamber is to release large bubbles and retain only small air bubbles in the mixture.
  • the air, milk and steam mixture forms the fluid that enters the mixing chamber.
  • Figure 4 shows the seal 130 of Figure 3A in more detail.
  • the various channel portions undergo a variety of different conditions when the mixing apparatus 100 is in operation.
  • the design of the channel portions and the seal thus influences the milk frothing function.
  • This design includes the width, cross sectional area and length of the channel portions, and also any flow restrictions along the channel portions.
  • the speed of the liquid (milk, steam and air) entering the mixing chamber influences the foam characteristics.
  • the milk frothing apparatus provides a design which enables a user to select milk frothing characteristics, or more generally different mixing characteristics or functions (as the invention is not limited to a milk frothing device).
  • Figure 5 shows in schematic plan view the arrangement described above, showing the first, inner, container 110 and the second, outer, container 120, and the first, second and third ports 150,175, 180 as well as the mixing chamber 160.
  • the first container is for receiving a first fluid, in particular a liquid, which is milk in this example.
  • the first port 150 will be termed “an opening” which leads to the first channel portion 210.
  • This first channel portion will be termed a “riser passage”.
  • the second channel portion 220 will be termed an "inlet channel”.
  • the external entry port 175 is for receiving a second fluid at a fixed position relative to the second container 120.
  • the first, inner, container 110 can be received in the second, outer, container 120 with at least two different orientations.
  • Each orientation forms a different set of passageways each including its own mixing chamber and riser passage.
  • Figure 6 shows a first example of an arrangement in accordance with the invention.
  • the first, inner, container 110 is schematically shown as square (when viewed from above), so that it can be rotated about a vertical axis into different orientations.
  • the two containers are preferably designed so that they only fit together with those two orientations.
  • the second, outer, container 120 has only one set of channel portions, whereas the first, inner, container has channel portions on two of its faces.
  • a first set of passageways can be formed, comprising a first opening 150, a first riser passage (not seen in plan view), a first inlet channel, and a first mixing chamber 160 when in the first orientation.

  • FIG. 6 shows in schematic form first and second closing members 600, 602. One of them is used to close the one of the first and second openings that is not in use. Thus, the riser passage that is not in use is isolated from the contents of the first, inner, container 110. There are various ways to implement closure of the unused opening, as discussed further below.
  • each set of passageways provides mixing of the liquid in the first, inner, container with the fluid provided to the external entry port 175.
  • the different sets of passageways may be for mixing different pairs of fluids.
  • one set of passageways may be for mixing milk from the first container with steam delivered to the external entry port of the second container for heating purposes. The use of steam limits the dilution of the milk.
  • the other set of passageways may be for delivering hot water to the external entry port for heating and dilution thus creating a different pair of fluids.
  • cold water may be delivered to the external entry port 175 simply for dilution purposes.
  • the different sets of passageways for example have different passageway dimensions and/or different flow restrictions.
  • Figures 6 and 7 show an example in which the first container 110 has a first, upright axis, and the first and second orientations are at 90 degrees with respect to each other about the first axis. This enables two adjacent sides of the first, inner, container which have channels in them, to be covered by the second container by designing the second container to substantially enclose three sides of the first, inner, container (not shown). This hides the visible channels portions of the first container 110.
  • Figure 8 shows an example in which the first container again has a first, upright axis, and the first and second orientations are at 180 degrees with respect to each other about the first axis. This enables only a single location to be needed for sealing the unused opening leading to the unused riser passage. Thus, a single closing member 800 is shown in Figure 8 .
  • the first container and second container lock together to ensure the passageways are correctly formed.
  • the locking position provides the required interaction between the two containers to define the first or second set of passageways in a sealed manner.

  • Figure 11 shows the example of Figure 10 viewed from the side of the first container where the unused channels are located.
  • the second set of passageways can be seen, comprising the second mixing chamber 160a, the second inlet channel 220a and the second riser passage 210a.
  • these passageways are not closed as they are not mated with the surface of the second container.
  • the second container 120 has at least one open side so that the first container is received as a lateral sliding fit into the second container through the open side. This is, however, only one way to couple the two containers together. An alternative is for one to be slid into the other from above.
  • a milk frothing apparatus also includes an air passage. If frothing is implemented in both orientations, there will be a first air passage which leads to the first mixing chamber in the first orientation and a second air passage which leads to the second mixing chamber in the second orientation.
